I have the Dell Pro 16 Plus PB16250 laptop.
The last update (New Tumbleweed snapshot 20260930 released) have corrupted my microphone.
I have solved it by downgrading of the sof-firmware package.
https://download.opensuse.org/tumbleweed/repo/oss/noarch/sof-firmware-2025.12.2-1.2.noarch.rpm
sudo zypper install --oldpackage /home//Downloads/sof-firmware-2025.12.2-1.2.noarch.rpm

Now it works again.

You may want to open a bugreport, else it may never get fixed.
